50-60GHz Reflective SPDT Switch
GaAs Monolithic Microwave IC
Description
The CHS2190a is a wideband monolithic diode
based reflective switch.
It is designed for a wide range of applications,
from military to commercial communication
systems. The backside of the chip is both RF
and DC grounds. This helps simplify the
assembly process.
The circuit is manufactured with a high
performance Schottky diode process, 1m gate
length (stepper lithography), via holes through
the substrate and air bridges.
